The monotypic fossil genus, Appendicisporonites, was described from the Neyveli Formation (Eocene, 56–40 mya) of Jayamkondacholapurum Well-12, Tiruchirapalli District, Tamil Nadu, India (Saxena & Khare 1992). The genus is characterized by subcircular, inaperturate and multicellular fungal spores. Each cell possesses a long process, processes septate or aseptate, with pointed or blunt tips, wall psilate. According to Kalgutkar and Jansonius (2000), the illustrated specimen appears to be related to the setose pycnidia found in some coelomycetes.

Type species: Appendicisporonites typicus R.K. Saxena & S. Khare
